Don't leave your heart at work : profiles of work-life interference and cardiometabolic risk
Katja Kerman, Sara Tement, Christian Korunka, 2021, izvirni znanstveni članek

Opis: The present study adopts an exploratory, person-oriented approach to investigate possible patterns of work-life interference. We examine work–life interference from a cognitive (i.e., thinking about work), behavioral (i.e., engaging in work-related behavior), and performance perspective (i.e., reduced functionality in private life, or work–life conflict) in order to identify profiles of employees that could potentially remain uncovered with variable-oriented research. Furthermore, as work–life interference relates to wellbeing and health, we were interested in exploring possible differences between profiles in emotional exhaustion, cardiometabolic risk, and health-related behavior. Self-report data on work–life interference and well-being, as well as objective health data, were collected from a heterogeneous sample of 289 employees. Four profiles with different patterns of work–life interference were identified. Out of the four profiles, two profiles reported moderate and high work–life interference (the Moderate Interference and High Interference profiles). The other two profiles revealed distinct combinations of moderate and low performance and behavioral interference (the Low Performance Interference and Low Behavioral Interference profiles). The High Interference and Low Behavioral Interference profiles were identified as risk groups in terms of cardiometabolic health, while the Low Performance Interference and Moderate Interference profiles showed low to no risk. Regarding work-related well-being, the High Interference profile showed the highest risk of emotional exhaustion.

Distrustful, dissatisfied, and conspiratorial : a latent profile analysis of COVID-19 vaccination rejection
Monika Lamot, Katja Kerman, Andrej Kirbiš, 2022, izvirni znanstveni članek

Opis: Trust in science and scientists, satisfaction with the national government, and endorsement of conspiracy theories are important factors in the decision to be vaccinated. In this study, we investigated whether there are different profiles of individuals depending on the above factors and whether they differ in their sociodemographic composition. We used data from Round 10 of the European Social Survey for Slovenia, employing a nationally representative sample of 1252 participants. Based on latent profile analysis, three distinct profiles emerged: Profile 1 expressed moderate trust in science, satisfaction with government, and high endorsement of conspiracies; Profile 2 expressed low trust and satisfaction and moderate endorsement of conspiracies; Profile 3 expressed high trust and satisfaction and low beliefs in conspiracy theories. In addition, Profile 3 expressed the strongest support for vaccination and Profile 2 the lowest. Our results suggest that distrust, dissatisfaction, and the presence of conspiracy theories are the “perfect storm” for vaccination rejection. In contrast, despite conspiracy theories, a certain level of trust and satisfaction may reduce vaccination rejection.

Innovative approaches to wear reduction in horizontal powder screw conveyors : a design of experiments-guided numerical study
Marko Motaln, Tone Lerher, 2024, izvirni znanstveni članek

Opis: Numerical simulations play a vital role in the modern engineering industry, especially when faced with interconnected challenges such as particle interactions and the structural integrity of conveyor systems. This article focuses on the handling of materials and emphasizes the importance of using parametric numerical analysis to improve efficiency, reduce wear, and enhance the structural integrity of horizontal screw conveyors. Through the utilization of the Design of Experiments, we systematically investigated critical parameters such as screw pitch, clearance, wear, rotational velocity, and additional structural factors. This examination was carried out within a well-defined parametric framework, utilizing a combination of software tools provided by the Ansys suite and Minitab. The findings demonstrate the effectiveness of the Design of Experiments analysis in achieving improved performance and provide valuable insights for engineers and researchers involved in the design of conveyor systems. Furthermore, this comprehensive approach clarifies how conveyor systems respond to changes in parameters and highlights the complex interaction between transported particles and the conveyor system. We present a detailed analysis that clarifies the complex relationships and dependencies among different parameters, providing engineers and researchers with valuable insights. By understanding the interactions of these factors, the methodology provides not only results but also a strategic framework for advancing conveyor system design and engineering practices.

Organizational maturity and sustainability orientation influence on DMS life cycle : case analysis
Sandra Jordan, Simona Sternad Zabukovšek, 2023, izvirni znanstveni članek

Opis: The topic of the article addresses the management of the document management system (DMS), which represents one of the important steps for organizations to speed up the implementation of business processes, achieve better control over documents, and ensure safer operations. When implementing and using DMS, the importance of the organization’s maturity shall not be forgotten, as it gives the organization a framework to evaluate and improve the overall effectiveness and efficiency of the organization’s DMS, which can contribute to better decision-making and increased productivity. On the other hand, sustainable-oriented organizations are likely to show interest in choosing, implementing, and using DMS. In the article, the impact of an organization’s maturity and the role of sustainability on the DMS lifecycle are researched. Results are presented based on a case analysis of Company X. Supporting the case analysis, structured interviews with the project leader on the clients’ and the project leader on the providers’ side have been performed, which shall give a deeper insight into DMS implementation and the importance of sustainability and organizational maturity, resulting in more successful DMS implementation and use.

Applying integrated data envelopment analysis and analytic hierarchy process to measuring the efficiency of tourist farms : The Case of Slovenia
Boris Prevolšek, Maja Borlinič Gačnik, Črtomir Rozman, 2023, izvirni znanstveni članek

Opis: This paper examines the efficiency of tourist farms in Slovenia by adopting an approach using a framework of non-parametric programming—Data Envelopment Analysis (DEA) and Analytic Hierarchy Process (AHP), combining the two because the DEA analysis by itself does not take into account all attributes, especially qualitative ones. The beforementioned two methods rank the farm tourism units with respect to their efficiency. By using the DEA method, an input- and output-oriented BCC and CCR model were introduced to upgrade the criteria by including the additional non-numerical criteria of the AHP. The results of the models showed that there are possible improvements on all levels of efficiency, as well as on the criteria of the additional offer of tourist farms, which were analyzed in the AHP model with additional criteria. According to the estimated efficiency, the ranking of tourist farms differed according to the two methods. Within the group of farms assessed as efficient by DEA, the AHP model allowed a more accurate ranking.

Directions for the sustainability of innovative clustering in a country
Vito Bobek, Vladislav Streltsov, Tatjana Horvat, 2023, izvirni znanstveni članek

Opis: This paper presents potential improvements through utilizing the cyclical nature of clusters by human capital, technology, policies, and management. A historical review of the formation and sustainable development of clusters in the US, Europe, Japan, China, and other regions is carried out to achieve this. The aim was to identify and assess the prominent occurrence cases, the central institutional actors, the indicators of their innovative activity, and the schematics of successful cluster management. The theory section covers current classification methods and typology of innovation-territorial economic associations. Consequently, a regression analysis model is produced to identify the potential dominant success factors in implementing the innovation policy of the most successful innovative clusters. Comments on the influence of these predictors on the competitiveness and level of innovative development of the 50 inspected countries follow. As a result of qualitative and quantitative analysis, an overview of the best world practice, the new vision, and its priorities are proposed to improve the efficiency at the level of management structures of innovation clusters.

Kristijan Brglez, Matjaž Perc, Rebeka Kovačič Lukman, 2024, izvirni znanstveni članek

Opis: Cities play a crucial role in achieving sustainable development. Decision-makers require assistance in developing city transformation plans amidst the emergence of various city models. A content analysis using concept mapping was conducted to examine smart, circular, and green city models. The analysis, supported by Leximancer, revealed that city models are evolving by adopting benefcial solutions from competitors, refecting a strong focus on sustainable development. Additionally, twentyfour research areas essential for implementing a circular city were identifed and validated. Furthermore, a conceptual model for a circular city was developed, incorporating the Defne-Measure-Analyse-Improve-Control tool and a problem-solving system. Testing the model on Maribor highlighted challenges in monitoring the transition towards circularity. The study validates the established model but emphasises the need for further research and case studies to verify its practicality. This scientifc research enhances the understanding of city models and their evolution towards sustainability, providing valuable insights for decision-makers and urban planners.
